T0 @ZZ whom t may concern.-

Be it known tliatl, WILLIAM I. McCnUs- LAND, a citizen ot the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Vllashing-ilachines; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

My invention relates to improvements in washing machines, and consists of certain improvements on the apparatus described in my Patents No. 577,765, dated February la, 1888, and No. 427,601, dated May 13, 1890.

The present invention is especially applicable to Washing plates, cups, dishes, and the like, without the necessity of placing the hand in the washing duid.

Reference is had to the accompanying drawings, in which the same parts are indicated by the same letters throughout the several views.

Figure l represents a central vertical section of the improved washing machine. Fig. 2 represents a section of the saine along the line .fr a: of Fig. l, and looking down, parts being broken away. Fig. 3 represents a plan view of the top of the machine, when about to be put into operation. Fig. t represents an inverted plan view of the water wheel for forcing the Washing fluid up between the two pans, and of the mechanism for revclvingthe same. Fig. 5 represents a similar section'to that shown in Fig. l, and represents the addition of a wire crate to the interior of the pan, the said crate being attach ed to and revolving with the central spindle. Fig. represents an inverted plan view of the Wire crate shown in Fig. 5.

The apparatus consists essentially of two pans the one fitting within the other, leaving a water-space between the two; a centrifugal water wheel for orcingjthe water up into this space, and through perfor-ations in the inner pan, the said inner pan being provided with a hole near the bottom thereof for the regurgitation of the water; a device for clamping the pans securely together at their upper edges, and for preventing the Water from {iowing out over the said edges;

and an extension of the inner pan upward, to prevent the water from splashing out over the top.

In the drawings, A represents the outer pan provided with abeading d at the upper edge thereof, and a projection a on the interior of the bottom to furnish a bearing for the lower end of the central spindle.

B represents the inner pan provided with a beading b inclosing the rubber gasket B, which rests on the beading ct of the outer pan. This inner pan B is preferably made sloping inward as at 17', and perforated at h2, the per torations being for the admission of the water, and the slope b being for the better influx thereof through the said perforations.

ln the bottom of the pan B, a round aperture b3 is cut, concentric with the spindle F, and over this aperture the corrugated, perforated plate B2 is placed. This plate is provided With a sleeve h4 which fits loosely over the spindle F. The corrugated plate is for the purpose of preventing the water f rom dow ing in a solid mass through the aperture b3, carrying with it crumbs and other solid particles from the dishes being washed, which might clog up the machine, while in use. The corrugated plate B2 is preferable to a flat strainer for the reason that a dat dish or plate would not, if placed upon the said corrugated disk, prevent the flow of fluid through the perforations therein.

On top of the two pans, an extension C in the shape ot a truncated frustum ot' a cone, or of a cylinder, is placed. This extension has a hook-shaped flange c at the bottom thereof, which springs over the beading b of the inner pan, and stittens the same. This extension C, the inner pan B, and the outer pan A, are then secured together by clamps D, and the whole makes a firm and waterproof joint. The extension C has the wire bead c similar to the bead a, and across the top thereot' the cross-piece E is laid. This cross piece is secured to the top of the apparatus by means of the spring clamp e. The spindle F is journaled in the said cross piece E and its lower end is provided with a hollow bearing for the stud or projection d. To the upper end of the spindle, the handle F' is detach` ably secured.

In the space between the bottoms of the in- IOC.

ner and outer pans, the water wheel I-I is mounted. This water wheel is provided with a number of inclined blades 72, connected to an inverted cup-shaped central portion 72.', which central portion is provided with a gear wheel h2 fitting loosely on the spindle F. The Water wheel II is driven by the gear wheelf rigidly attached to the bottom of the spindle F, which wheel f gears in a smaller gear wheel k mounted on the spindle 7a2 projecting inward from the bottom of the pan A. Rigidly attached to this gear wheel 7a, is a larger wheel 7c', which meshes in the smaller wheel h2 integral with the centrifugal water wheel H. Thus it will be seen that the spindle F, operated by the handle F, turns the gear wheel f, which turns 7o, and 7o and that a very rapid motion is transmitted to the gear wheel h2 from the gear wheel 7s'.

The operation of the device is as follows:- The dishes are placed in the inner pan as shown in Fig. 3, and then the washing fluid, preferably soap and hot water, is poured into the inner pan, until the dishes are covered. The fluid Hows down through the perforated plate B2 and the holes b3 into the space between the pans, seeking its own level in the space AO between the sides of the pans. Now it' the water wheel H be turned in the direction indicated by the arrow in Fig. 4l, the water will be thrown away from the center of the wheel, and will be forced up into the space A until it reaches the perforations b2, when it will be sprayed back into the inner pan, pass downward through the dishes, and out tothe Water wheel, thus passing in and around the dishes and thoroughly washing the same. When the dishes have been Washed sufliciently, the clamps D are unhooked, the detachable handle F is taken off, and the pan B is lifted out slowly, allowing the water therein to drain through the corrugated perforated plate B2, and hole b3 into the pan A. Or the pan B may be placed on the top of a bucket and allowed to drain into the same. The Washed dishes may then readily be wiped.

In the device shown in Figs. 5 and 6 in addition to the features shown in Figs. 1 to 4, a wire crate M is mounted in the inner pan B, and is rigidly attached to the revolving spindle F by means of the collar and set screw m3. The wire framework consists of the wire rings m, m', and m4, and the vertical wires m2. A rackN to hold the plates, saucers, risc., may also be placed in the bottom of the crate if desired.

The water wheel is omitted from Fig. 5 for the sake of clearness in the drawings.

The operation of the device shown in Figs. 5 and 6 is the same as that described with reference to the device shown in Figs. l to 4:, except that the crate containing the dishes is revolved simultaneously with the spindle F, and the dishes pass through the water horizontally, while the water is itself flowing downward through the dishes, and thus an increased washing eifect is obtained. When the washing is complete, the cross-piece E is lifted off, and the spindle and crate are lifted out, carrying the dishes with them, which latter will rapidly drain dry enough to be ready for wiping.

It will be obvious that many modilications might be made, which could be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
